IconoMaker allows you to edit icons. It supports the new icon format introduced in Windows XP (employs smooth transparency and other visual effects). Using this program you can create and edit icons in either standard or custom sizes, with color depths up to 32-bit True Color with 8-bit alpha channel. Paint tools include: color replacer, color selector, spray can, pencil, brush, flood fill, text tool, line tool, rectangle, curve and ellipse. For Windows XP icons, you get to use semi-transparency.
